macOS SwiftPM Runner

Quick Start

Use this skill when Package.swift is the primary entrypoint or when SwiftPM is the fastest path to a reproducible result.

Workflow

1. Inspect the package.

   • Read Package.swift.
   • Identify executable, library, and test products.

2. Build with SwiftPM.

   • Use swift build by default.
   • Use release mode only when the user explicitly needs it.

3. Run the right product.

   • Use swift run <product> when an executable exists.
   • If multiple executables exist, explain the default choice.

4. Test narrowly.

   • Use swift test.
   • Apply filters when a specific test target or case is known.

5. Summarize failures.

   • Module/import resolution
   • Package graph or dependency issue
   • Linker failure
   • Runtime failure
   • Test regression

Guardrails

• Prefer SwiftPM over Xcode when both exist and the package path is clearly simpler.
• Do not assume an app bundle exists in a pure package workflow.
• Explain when the package is library-only and therefore not directly runnable.

Output Expectations

Provide:

• the package products you found
• the command you ran
• whether build, run, or test succeeded
• the top blocker if not
